This may be a long shot but thought you might like to know. There was Benjamin Jump in Baltimore Co., Md. who was dead by 9 June 1752 when bond was adm. on his estate. The reason I think he might be connected is that William Lowe was, also, there. Many of the Lowe family went to Western VA>KY. My line of the Lowe family went to GA. This data came from "Baltimore Co. Families 1659-1759" - Robert W. Barnes - Clearfield Pub. Hope this will help. B.J.Gilmore
